If a ball is thrown from a tall building, how tall is the building if it takes 6s for the ball to land?

Physics

Answer:

the answer is 352.8m

Explanation:

Since the gravitational constant is denoted as g

g = 9.8  \:  \frac{m}{ {s}^{2} }

and the ball needed 6 seconds to land, so we can calculate the height of the building as:

h = 9.8  \:  \frac{m}{ {s}^{2} } \times {(6s)}^{2}  = 9.8  \:  \frac{m}{ {s}^{2} }  \times 36 {s}^{2}  = 352.8m

A wire is stretched right to its breaking point by a 5000 N force. A longer wire made of the same material has the same diameter
leva [86]

Answer:

Equal to 5000N

Explanation:

The stress on the material is defined by force per unit of cross-sectional area. So it depends on the force and the diameter of the wire, which is the same for both wires. The material that defines the breaking point, is also the same. Therefore, both wires have their breaking point the same at 5000N. The wire length plays no role in here.

What must the diver's minimum speed be just as she leaves the top of the cliff so that she will miss the ledge at the bottom, wh
Dafna1 [17]

Answer:

1.08 m/s

Explanation:

This can be solved with two steps, first we need to find the time taken to fall 9.5 m, then we can divide the horizontal distance covered with time taken to calculate the velocity.

Time taken to fall 9.5 m

vertical acceleration = a = 9.8 m/s^2.

vertical velocity = 0, (since there is only horizontal component for velocity, )

distance traveled  s = 9.5 m.

Substituting these values in the equation

s= u \timest+0.5at^{2}

t= \sqrt{\frac{2s}{g} }

t=\sqrt{\frac{2\times9.5}{9.8} }

⇒ t= 1.392 sec

Velocity needed

We know the time taken (1.392 s) to travel 1.5 m,

So velocity = 1.5 m / 1.392 s = 1.08 m/s

hence velocity of the diver must be at least 1.08 m/s
